Detection and amplification of spin noise using scattered laser light in a quantum-dot microcavity
A. N. Kamenskii, M. Yu. Petrov, G. G. Kozlov +7
Fundamental properties of the spin-noise signal formation in a quantum-dot microcavity are studied by measuring the angular characteristics of the scattered light intensity. A dist…
Stimulated spin noise in an activated crystal
M. M. Sharipova, A. N. Kamenskii, I. I. Ryzhov +5
In the spin noise spectroscopy, the magnetic susceptibility spectrum is known to be provided by the spin-system untouched by any external perturbation, or, better to say, disturbed…
Nuclear spin relaxation in n-GaAs: from insulating to metallic regime
M. Vladimirova, S. Cronenberger, D. Scalbert +7
Nuclear spin relaxation is studied in n-GaAs thick layers and microcavity samples with different electron densities. We reveal that both in metallic samples where electrons are fre…
Optical spin noise spectroscopy: application for study of gyrotropy spatial correlations
G. G. Kozlov, V. S. Zapasskii, I. I. Ryzhov
The single scattering theory is applied to spin noise spectroscopy (SNS). The case of two Gaussian probe beams tilted with respect to each other is analysed. It is shown that SNS s…
Single-shot measurement of transient nuclear magnetization with spin-noise spectroscopy in n-GaAs microcavities
I. I. Ryzhov, S. V. Poltavtsev, K. V. Kavokin +9
We exploit spin noise spectroscopy (SNS) to directly observe build-up of dynamic nuclear polarization and relaxation of a perturbed nuclear spin-system to its equilibrium state in…
Noise spectroscopy of the optical microcavity: nonlinear amplification of the spin noise signal and giant noise
S. V. Poltavtsev, I. I. Ryzhov, V. S. Zapasskii +1
The spin-fluctuations-related Kerr rotation noise of the optical beam reflected from a microcavity with a quantum well in the intermirror gap is studied. In the regime of anti-cros…
Anti-mirror reflection of a bounded plane optical waveguide: string model
P. Yu. Shapochkin, Yu. V. Kapitonov, G. G. Kozlov
The effect of anti-mirror reflection from a bounded plane optical waveguide used earlier for observation of slow light in a Bragg waveguide is considered. A theory of the effect is…
Optics of spin-noise-induced gyrotropy of asymmetric microcavity
S. V. Poltavtsev, I. I. Ryzhov, R. V. Cherbunin +5
The optical gyrotropy noise of a high-finesse semiconductor Bragg microcavity with an embedded quantum well (QW) is studied at different detunings of the photon mode and the QW exc…
Spin noise spectroscopy of a single-quantum-well microcavity
S. V. Poltavtsev, I. I. Ryzhov, M. M. Glazov +6
We report on the first experimental observation of spin noise in a single semiconductor quantum well embedded into a microcavity. The great cavity-enhanced sensitivity to fluctuati…
Resources of polarimetric sensitivity in spin noise spectroscopy
P. Glasenapp, A. Greilich, I. I. Ryzhov +4
We attract attention to the fact that the ultimate (shot-noise-limited) polarimetric sensitivity can be enhanced by orders of magnitude leaving the photon flux incident onto the ph…
Bragg Reflection Waveguide: Anti-Mirror Reflection and Light Slowdown
G. G. Kozlov, V. S. Zapasskii, Yu. V. Kapitonov +1
The effect of the light group velocity reduction in dielectric Bragg reflection waveguide structures (SiO/TiO) in the vicinity of the cutoff frequency is studied experiment…
